I don't own it, but I can give you a few links.
The manual - http://www.zanchetta.net/default.aspx?Categorie=ECHIQUIERS&Page=documentations
(Choose Saitek as the manufacturer. The Centurian manual is available in both French and English.)
The Overtom site: https://tluif.home.xs4all.nl/chescom/EngKasCent.html
Strength estimates: https://schach-computer.info/wiki/index.php/Wiki-Elo-Liste_En
(I don't think there's any easy way to find out the strength of the "standard level 1 second". Also, note that the Elo list shows the Centurian with three different processor speeds.)
Anybody owning this?
Got this chess computer before 2000 ( speaking about years, obviously, not rating, will be this rating in another life), when i was 15-16 or something. At this time i was crushed everytime. I plugged it again. First impression, woaw, how could I let this taking the dust during all these years, this is a great tool to learn and have fun outside chess.com.
But the real question is, do anybody know what rating is the standard level 1second? Have been playing several times this week, and I am approaching balanced endgames, I am confident to defeat it in a near future, it s my very own personal challenge these days.
So anybody got details on this beautifull chess computer ? ( could download quick start manual on the internet, but I would be glad to get any more details concerning it)
